We were booked coach on a OAK - OGG flight without seat confirmation. After reading countless stories of couples seated apart, I called HA's 800 number to inquire if any seat assignments could be made in advance. Several times I was told "no." Then one said I could pay the additional amount for the preferred seats. I wanted my hub's okay, so didn't commit. Next day I called to request the minor upgrade, but was told it wasn't possible until check in. Was finally lucky to get a CSR who when to bat for me, and pushed his supervisor to allow us to be seated together. What a sweetheart! Fingers crossed we will keep our seats as we celebrate 25 years together.
